This Minus 1 Day icon is part of an icon pack of 80,800 web icons. Icons are available in PNG, SVG, CSS, PDF, and EPS formats, as a font, and in other vector formats. Unlike other icon packs, our web icons are designed by a single designer, guaranteeing the consistent style and quality.
It's what looks like a small, desktop calendar, with two rings on the top to change the date. It has "- 1d" meaning to subtract one day, written on the front of the calendar, to be an icon representing the subtraction of a day for other calendar purposes.
